First, at least on x86, the kernel will look for the 'installkernel'
executable first in your own ~/bin/, so if you have that then it will
override /sbin/installkernel.

Second, you don't have to let the kernel choose; just run
/path/to/myinstallkernel $kernelversion path/to/boot/image System.map
(Disadvantage: path/to/boot/image varies depending on arch.)
